I have a linux server that is only hosting one site , and although the httpd and mysql are working well , then the server load is high and when I restart the server the server load is high till the swap accelerates to 100% and then it uses the memory alot.

Not good ....
I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ?
Question 2 : Why i don't find high usage process in top command ?
Question 3 How can i resolve this problem ?
I have a cPanel server with 4GB RAM
My server hangs time to time, once or twice a day. This is the last status when it happens.
Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %
When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.
So I "killall -9 httpd", I had to do it 30~40 times
#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.
Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.
At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)
i have a problem with my server it is a Xeon with 2Gb ram, i have a igh swap usage and when it reach the size of 4gb that i have set it go in kernel panic, this is the actual value

I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
for the last few days, i am facing high memory usage up to 90%.
Memory usage get's high, even if i don't have many visitors online. I have to restart httpd to get the memory to normal. some times, server loads, get's high aswell.

as it's taking alot of memory. i don't see this before.
I was getting high load on one of our test machines -- it was high enough to where I couldn't ssh in. However, I happened to have a shell open at the time with top running. Load was very high and swap was full. -- afterwards, when I check /var/log/messages it looks as if the load affected the time (see below).
1) At first I was guessing that the load somehow affected the clock, but you'd think it would slow it down -- but apparently the pace of time was quicker?
2) perhaps the time was wrong in the first place - then upon reboot, ntp sync'd up properly.
3) time was originally correct but after the high load, it somehow erroneously sped up the ticks
Then again, from googling around someone on another forum was saying that the computer clock chip shouldn't ever be affected.
So my question isn't about what cause the load, but why was there a time descrepancy in /var/log/messages, and was it related to the load?

I have server load like 40.
Nothing lags.
Server has RAM usage 20% and CPU usage goes up to 25%
Swap isnt used at all.
Should I be afraid of server crash incase server load goes up to 60 or 80 without ram and cpu usage rising that much?
Am using Hypervm,my all vms are not using more than 512 MB memory but when i click on server as localhost the there is show maximum memory usage I have total 8 GB it always show 5-6 GB usage and never drop down, How can I fix this matters?
View 7 Replies View RelatedI have a Drupal site with around 1000 visitors/day on a basic VPS. (HyperVM with lxadmin) Burstable RAM is 384MB and my site reachs it.
is this normal for a site like this?
anything that I can do to decrease the memory usage?
I purchased a VPS at wiredtree to upload a site that is in the works so that it would be "ready" once it was launched (had it sitting on a shared server before). So I have this domain on there, as well as a small wordpress blog. In total I'm get a very miniscule trickle of visitors to these websites (as they are not officially launched), around 100 visits per day, many of which are only 1 pageview visits.
My problem is, my server is already idling over its memory limit of 256mb. This is causing major slowdowns, and processes like cpanel are constantly be killed and I can't login.
Does anyone have any idea what is causing my high memory usage? I just can't image that the visitors I am getting are doing much, as for the majority of the day I have absolutely no one viewing my domains, yet my memory usage is still over the limit.
Wiredtree support says its up to me to optimize my msql/php scripts etc for low mem usage, but I don't see how this will help when there is no one using them in the first place.
I installed kloxo on a fresh CentOS installation, not the hostinabox template
I have high memory usage though as seen here

I'm currently running vBulletin & two wordpress powered blogs on my box. Number of simultaneous users is about 200~250 and about 15~20 logged in users.
The memory usage is constantly in the range of 1.8 GB - 2.00 GB. Considering that total physical RAM my box has is 2 GB, the memory usage, I believe is exceptionally high.
The same site was running very well on shared hosting environment and also on VPS [with just 512 MB RAM] very fine.
What should I do to bring the memory consumption to minimum (required to run the site well?)
We are currently running plesk 11.5 and over the last few months, the apache memory usage has been very high. On investigation we have gone through the logs and we can't find a cause.
I can issue a service httpd restart and the memory drops for about 30 minutes and then we see the apache memory grow to almost 1.5 - 2GB. Why this keeps happening?
I was wondering is someone can shed some light on a curious situation for me. I am running a linux server (Gentoo) and the CPU usage spikes to 90-100% but the load of the server when viewed by top is only 0.4 - 1.5 (max). The memory is OK with .5 gig free and there is no paging going on. So my question is: Is this server over used or not?
Below is the output of top 3 times over aprox 2 min... please enlighten me... :-)

I have a server that I have had for a little while now that was runnning perfectly fine. All of the sudden it started just using up a ton of the memory and started using up swap. This has caused the server to slow down and e-mail to stop working. I would upgrade to more memory but I suspect it is someone on the server doing something they shouldn't be. My only reasoning for this is due to the fact that this problem just suddenly arised. I cannot for the life of me determine where this ram usage is coming from.
Here are a few of the errors I have recently got just while logging in..
RIGHT after logging in...
id: cannot find name for group ID 0
id: cannot find name for user ID 0
[root@www root]# top
top: Unknown terminal "xterm" in $TERM
[root@www root]# killall -9 spamd
bash: /usr/bin/killall: Too many open files in system
I have added 2 screen shots as well. First one (top1) is what happens once I can get the command "top" to actually run (normally takes quite a few tries). Second attachement (top2) is after I sorted by mem usage...
My server is very slow, High CPU, High Apache load....
I got a new server and i had setup a script on it.
No server tweaks has been done.
I run a filehosting site so it gets very slow when traffic is high.
Here is some info:

I dont know much about server managment...
how to fix this so server doesnt go slow?
if there is any specific way (maybe logs) to see what is using the swap memory of a dedicated server..
its a server with 8GB ram.. it has 60% of memory used, and a constant swap memory usage of 30%.. i thought that in normal conditions swap memory was not used..
its a centos / cPanel/WHM based server
I've got a dedicated with LW.
I've had it for a while and during that time I've never seen the swap memory go over 20%.
A month or so ago, I had the server upgraded to 8GB of ram to make room for more planned sites.
Since then, the swap memory has gone rampant. It regulary goes to 93% used with less than 20% of the regular ram and really no load on the server.
I've contacted support twice about it and was told don't worry it's normal.
From what I've read in the cpanel forum, no it's not normal and may in fact be caused by bad ram chips and if it hits 100% could freeze the server.
There are no processes or users causing it, so It's something else.
Has anybody had this type of problem that they resolved and could share what they did to resolve it?
Since a short while back my server memory usage is 100%. The amount of
visitors decreased so the memory should be lower in consumption than before.
I suspect a newly installed script could have bugs or misuse of the
server by hackers. I don't know how to see on the server what script or
what part makes the memory use so high. I see Apache is very high but
I'm on VPS.
Technical data........
Currently i have a small server with 512 Mb of ram i doing some minor hosting..
sometimes..my free memory is only left with 15 mb..is there a concern down here?
is there anyway i can find out what are using up my memory..? And should i just upgrade to 1Gb instead?
Somtimes my mail queue ..will also take up like 20 to 30 mb of memory as they keep on trying to resend themself
I've hired *name* to take care of my server, but it's just getting so frustrating, as it seems they can't fix my server/optimize it correctly.
I just want some input as to what the problem is here.
I got them to install lighttpd along with xcache.
After about 15-18 hours, the server's CPU slowly increases to be using 90-90%, giving me the 500 Internal Server Error.
I've asked them to optimize xcache and lighttpd, but I keep getting these responses:

The should be pretty optimized. Xcache has limited optimization features.
Quote:
Lighttpd itself is pretty optimized, the problem is php. Php runs as its own binary and theres not many parameters that can be tweaked.
Is that even correct?
-------------------------
So I got them to enable apache, and disable lighttpd.
This time, it's the other way around.
My ram get's completely used up, forcing the server to use Swap; making the load shoot to 50+. CPU usage is fine the entire way.
-------------------------
This has been going back and forth, enabling/disabling lighttpd and re-enabling apache but a problem always comes up each time.
Am I asking for too much?

I'm having an issue with what I believe is Apache. Things will be running nicely, then all of a sudden things will just 'blow up'. Apache seems to fork a bunch of new processes, and it starts ripping into the memory. I've had it essentially eat through all the free memory and swap, and the system will then freeze up as there's no more memory. This is a CentOS server running CPanel, the configuration had been up and running for a long time without problems then this suddenly started happening.

Viewing your current resource usage
Log in via SSH, I normally use the Putty client for this.
Commands:
top: your current server load & resource usage.
ps aux: all your processes & which ones are using the most memory/cpu
free -m: allocated memory, usage & free memory
Is the command line really *easy* once you get used to it?
